Round 1:

For some reason supersport didn't show the first session of today's athletics but here we are:

Usain Bolt - 10:20s - No comment.

Asafa Powell - 10:16s - The former world record holder said he had suffered with stomach problems after his breakfast but was happy enough.

Tyson Gay - 10:22s - "It feels good," he said." "I felt a little sluggish but my body has woken up now."

AND, who who who are you? - Tyrone Edgar - 10:13s as the fastest runner from Heat 1.

The final is tomorrow at 16h30 SA time. Yes, that is during the rugby...
